Episode 5: Membrane Chemistry Explained

In this episode of ZwitterCo Unfiltered, Jon Goodman is joined by Lyndsey Pence, industry-recognized membrane nerd, to dive into the fundamentals of membrane chemistry, membrane manufacturing, and what makes ZwitterCo’s zwitterionic technology different from conventional filtration membranes. The conversation explores the evolution of membrane technology from early cellulose acetate RO membranes to modern thin film composite RO membranes and various UF membranes used in today’s dairy and food processing applications. Jon and Lyndsey also discuss how membrane structure impacts fouling resistance, protein retention, lactose passage, cleaning requirements, and long-term productivity.What You’ll Learn:How ZwitterCo’s zwitterionic membranes differ from conventional membranes  How membrane structure impacts protein retention and lactose passage  The difference between asymmetric and thin-film composite membranes  Why pore size distribution matters in ultrafiltration performance  How membrane manufacturing conditions influence separation characteristics  The role of zwitterionic chemistry in resisting fouling and improving productivity
